Answer 2

Option CA is not radius.

• Radius is the line drawn from the centre of the circle to any point on the circumference of the circle.
• The lines AB and BG join the centre of the circle with the circumference and hence is the radius.
• The line CA joins one point on the circumference to another point on the circumference of the circle by passing through the centre of the circle.
• Hence, the line CA is diameter and not radius.
